A greenhouse screening method for resistance to gray leaf spot in maize
… mid-Atlantic states. A new greenhouse assay method with filter paper discs of C. zeaemaydis mycelia has been developed to evaluate corn germplasm for resistance to GLS. Mycelial inoculum obtained from cultures of mycelia in liquid malt media was pipetted at 100 ul samples onto each filter …

Design of a microscopy-based screening method for stomatal development genes in <i>arabidopsis thaliana</i>
… to create a reverse genetics, microscopy-based screening method to identify Arabidopsis genes important in guard cell development. It was hypothesized that gene coexpression analysis would facilitate identification of gene candidates involved in stomatal development. Plants harboring mutations …

Selection of Drought-Tolerant Soybean Lines Using a Field Screening Method and Identification of QTLs for Slow Wilting and Nitrogen Fixation Associated With Drought-Tolerance
… there is little information on effective methodologies for phenotype screening in the field, and some QTLs have been identified for drought tolerance. Field screenings under drought and irrigated conditions are necessary to detect drought tolerant lines. In addition, QTLs and molecular …

Small signal analysis of power systems: Eigenvalue tracking method and eigenvalue estimation contingency screening for DSA
… The first part presents the eigenvalue tracking method for power system stabilizer (PSS) placement. Traditional methods for determining PSS placements are based on the analysis of the interconnected system. However, the design of the PSS is based on a simplified single machine infinite bus (SMIB) …

Regression based principal component analysis for sparse functional data with applications to screening pubertal growth paths
… such growth paths. However rigorous quantitative methods are largely missing in the literature. In the first part of this dissertation, we proposed a new screening method based on principal component analysis for growth paths (sparse functional data). An estimation algorithm using alternating …

Process development and scale-up from shake flask to fermenter of suspended and immobilized aerobic microorganisms
… measurement in shake flasks is introduced as a screening method to characterize the behavior of microorganisms exposed to stress factors such as carbon starvation, anaerobic conditions, organic acids, osmolarity and pH. It is evaluated and compared with the standard measuring methods, exhaust …

Innovative molecular methods for fish species differentiation
… of a proof-of-principle study in which a rapid screening method for various market-relevant fish species have been developed. A DNA microarray was established using a set of 100 universal oligonucleotide probes. DNA probe signal patterns were observed to be speciesspecific, enabling species …

Enzymes as Drug Targets in the Isoprenoid Biosynthesis Pathway: Structure, Mechanism and Inhibition
… of enzyme inhibitor complexes. A high throughput screening method was developed, by which novel potent inhibitors against farnesyl diphosphate synthase (FPPS) and Staph. Aureus dehydrosqulene synthase (CrtM) were identified. We also conducted thermodynamic study of FPPS inhibition, which revealed …

The significance of antibody production in human renal transplantation
Screening for HLA specific antibodies is an important part of laboratory testing for transplantation. The conventional technique for screening is complement dependent lymphocytotoxicity. The development and increasing use of the sensitive flow cytometric crossmatch technique has meant that this …

DEVELOPING SMALL-MOLECULE PROBES AND INHIBITORS FOR ADP-RIBOSE-BINDING PROTEINS
… but no WWE domain inhibitor or relevant screening method has been reported. Therefore, for both macrodomains and WWE domains, probes and inhibitors are highly desired to elucidate their function and druggability. In Chapter 2, I developed a robust fluorescent polarization (FP) assay that …

Molecular signalling in Lupinus albus-Rhizobium lupini symbiosis
… in Lupinus remains to be determined. Using a screening method based on the in vitro ability of the flavonoid inducer to adsorb onto the membranes of its symbiont, indicated that derrone, wighteone and lupiwighteone were adsorbed most onto R. lupini membranes. A second screening method, based …
